check socket creation errors against PGINVALID_SOCKET

Browse Source 
Previously, in some places, socket creation errors were checked for
negative values, which is not true for Windows because sockets are
unsigned.  This masked socket creation errors on Windows.

Backpatch through 9.0.  8.4 doesn't have the infrastructure to fix this.
